GeForce GTX 260 vs Radeon R9 M380

Intro

The GeForce GTX 260 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM is set to run at a frequency of 999 MHz on this particular model. It features 192 SPUs along with 64 TAUs and 28 Rasterization Operator Units.

Compare all of that to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 3136 (9%)

Pixel Rate

The GeForce GTX 260 will be a bit (more or less 1%) better at FSAA than the Radeon R9 M380, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 260 16128 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 128 (1%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
